well the ones in MAME area

The first letter of the 3 letter codes is the region, the 2nd is some kind of 'type' for different cabinet types that require different game code (different # players, different mirror setups etc.) and the last is the revision.
So our Japanese Total Vice is 'JAD' is Revision D, meaning there are 3 undumped Japanese revisions at least.
Battle Tryst is (ver JAC) so presumably the new dump is going to be either JAA or JAB, meaning even there we likely still have a missing revision
so yeah, there are actually a fair few revisions of these. Poly Stars is JAA so possibly there are no other revisions of that, or if there are we have the oldest one.
Even for other 'failed' systems, like Hyper NeoGeo 64 we're clearly missing some game revisions based on the ROM labels etc. If anything it's going to be more common with CD games because it was easier to issue new media.
